What:
-----
This program plays a simple guessing game.
A random number is chosen between LOWER_LIMIT = 1 and UPPER_LIMIT = 100.
The player is given a set of bounds and must choose a number
between them
If the player chooses the correct number, he wins.
Otherwise, the bound are adjusted to reflect the
players guess and the game continues.
Input: guesses entered by user.
Output: Prompt to the user containing the adjusted boundaries.
Restriction: The random number is generated by the statement
rand ( ) % 100. Because rand( ) returns a number 0<=rand()<=maxint,
this slightly favors the lower numbers.
